Which coordinate plane shows triangle ABC after
a reflection over the y-axis?
Answers
A=5
B=4
C=7
The rule for coordinates for a reflection over the y -axis is:
( x, y ) → ( −x, y )
The coordinates plane for the triangle ABC after a reflection over the y-axis is
A(5, -2), B(4, -4), and C(6, -4).
What is reflection?Reflection is a transformation that flips a shape in a mirror line also called a line of reflection so that each point is the same distance from the mirror line as its reflected point.
The rule for coordinates for a reflection over the y -axis is:
( x, y ) → ( −x, y )
We have,
The following coordinates:
A = (-5, -2)
B = (-4, -4)
C = (-6, -4)
Since the rule for coordinates for a reflection over the y-axis is
(x, y) ⇒ (-x, y)
We have,
(-5, -2) = (5, -2)
(-4, -4) = (4, -4)
(-6, -4) = (6, -4)
Thus the coordinates plane for the triangle ABC after a reflection over the y-axis is A(5, -2), B(4, -4), and C(6, -4).

If a store raises a coffee mug's price from $6.25 to $8.77. The price increase was 40.32%. Option C is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that, A retailer marks up the price of a coffee mug from $6.25 to $8.77.
We have to find the percentage by which the price increase,
% increment = New rate - old rate / old rate × 100
% increment =(8.77 - 6.25)× 100
% increment =40.32%
Thus, if a store raises a coffee mug's price from $6.25 to $8.77. The price increase was 40.32%. Option C is correct.

Write equation of a line parallel or to a y=2x+3 that passes the ordered pair (3,6)
Answers
Answer:
y = 2x
Explanation:
To write the equation of a line u use the formula y = mx + b, where
y = y coordinate
m = slope
x = x coordinate
b = y intercept
One thing about parallel lines is that they always have the same slope. If you want to find a line parallel to y = 2x + 3, then the parallel line will also have a slope of 2.
So far, then, the equation would look like this: y = 2x + b
To find the y-intercept, we substitute in the values from (3,6) into the equation because the line passes through that point. So:
y = 2x + b
(6) = 2(3) + b
6 = 6 + b
6 - 6 = b
b = 0
Since the y-intercept is 0 (so the line passes through the origin), it doesn't need to be written on to the end of the equation.
y = 2x + 0 is just
y = 2x
That's your final equation! hope this helps!
60 people were asked the colour of their car and the pictogram shows the results.
a) 16 cars are red. Complete the key.
b) How many cars are silver?
KEY: One circle represents __ cars
Red = 4 circles
White = 3 circles and a half
Silver = 5 circles and 3/4
Grey = 1 circle and 3/4
Answers
The number of silver cars in the pictogram is 23.
How many cars are silver?If 16 cars are red, then, each circle represents 4 cars.
If each circle represents 4 cars, then, each quarter of a circle represents 1 car
White car = 4 + 4 + 4 + 2
= 14 cars
Silver = 4 + 4 + 4 + 4 + 4 + 3
= 23 cars
Grey = 4 + 3
= 7 cars
Total cars = red + white + silver + grey
= 16 + 14 + 23 + 7
= 60 cars
It can therefore be concluded that silver cars is 23 in number.

Answers
The main point is that you want to round 8.154 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 8.154. To eliminate the last digit in 8.154, we use the following Two Decimal Places Rules to get the answer:
Two Decimal Places Rule #1: If the last digit in 8.154 is less than 5, then remove the last digit.
Two Decimal Places Rule #2: If the last digit in 8.154 is 5 or more and the second to the last digit in 8.154 is less than 9, then remove the last digit and add 1 to the second to the last digit.
A 381 foot cable runs from the top of a radio tower to a skate in the ground. If it hits the ground 167 feet from the base of the tower , what is the angle of elevation that is makes with the ground?
Answers
Answer:
64°
Step-by-step explanation:
Using Pythagoras rule :
Cosθ = adjacent / hypotenus
Adjacent = 167
Hypotenus = 381
Cosθ = 167 / 381
Cosθ = 0.4383202
θ = Cos^-1(0.4383202)
= 64.003
Hence, angle of elevation = 64°

Answer:
The winning time increased by an average of 0.4 second per year from year 2 to year 4.
Step-by-step explanation:
I just took the quiz
The winning time for a race displayed in the table would be:
A). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.
Find the increase in winning time:Given that,
Year Winning Time(seconds)
1 27.5
2 28.4
3 28.7
4 29.2
5 29.44
The total change in the time = (0. + 0.3 + 0.5 + 0.24)/4
= 0.485 seconds
If we round off, it becomes 0.5 seconds.
Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.
